If you get a PHP-related error (other than something to the effect of "program not found"), then your problem is a typo in the code.

如果您得到一个与php相关的错误(除了“未找到程序”之类的结果)，则问题是代码中的输入错误。

As a result, if someone comes across an error (for example, a 404 page Not Found, 403 Forbidden, or 500 Internal Server error), he will only see an ugly error code page.

因此，如果某人遇到一个错误(例如，404 Page Not Found、403 Forbidden或500 Internal Server Error等错误)，他将看到一个难看的错误代码页面。

youdao

Everyone knows that if you try to access a page that doesn't exist, the server will throw you back 404 page not Found, or if you mess up your rails code, you will get a 500 Application Error.

每个人都知道如果打开一个并不存在的页面，服务器会返回一个404错误页面。如果你的Rails程序出错了，会返回一个500应用程序内部错误的页面。

The "warhead" names appeared as links, most leading to 404 error messages of pages not found, but some leading to pages of raw programming code.
